Clearly LPG is vitually half the price of petrol (benzine) which is 1.9 lev approx.
there are Gasstanzia all over the place much more common than in the UK. As much for cooking as for driving, but LPG conversion is very common due to not being able to afford the higher price of petrol. There is also the compressed natrual gas alternative which a lot of taxis use but those stations are quite few and the conversion costs more. Once done the CNG gas is very cheap.
